Notes
Loudness circuit connections. Connect high-frequency compensation
capacitors between the LCT1/RCT1 and LIN/RIN pins, and connect low-
frequency compensation capacitors between LCT2/RCT2 and Vref2.

These inputs must be driven by low-impedance outputs.

Fader outputs. The front and rear can be attenuated independently. The left
and right attenuation levels are identical.
These are low-impedance outputs, since they have built-in operational
amplifiers.

VDD/2 voltage generation block. A capacitor must be connected between Vref1
and VSS to suppress power supply ripple.
Vref1
36
Common pin for the main volume control block, fader block, tone control
block, gain control block, and input switching block.
Since the capacitor connected between Vref2 and VSS becomes the residual
resistance when the volume control is set to maximum attenuation, the value
of this capacitor must be selected carefully.
The voltage applied to this pin must never exceed VDD.
